Gardner LW5

So, today I just took possession of our new (to us) boat that will hopefully take us to lands far away. It is a Roberts 57 built under Lloyds supervision by a chap who spent his life on the sea, and it shows in the systems which are all chosen to be simple and reliable.

The engine is a venerable slow reving Gardner 5LW 75 dhp (draught-horse power) which externally looks like it could have left the factory a few months ago.

I guess I was just hoping to hear from others who may be running a Gardner and may have information to share.

Re: Gardner LW5

Lots of Gardners hanging about in sheds and fishing boats as a remnant of all the Gardners in the old trolley buses. Not so many 8lx s but heaps of 6lxs of different power ratings .

Re: Gardner LW5

Congratulations, the Gardner would have to be the most reliable & easy to live with High speed Diesel built, unlike some of the K Mart engines that feature on this Forum.

1. steaming Max R.P.M?

2. Raw or Freshwater Cooled?

3.2UC Gardner box still fitted?

4. G/box Ratio?

Unlike Modern engines the Older your Maintenance Fitter the Better, the younger generation are not taught the diagnostic skills needed.

Re: Gardner LW5

Congratulations on your new boat!
I hope my next boat is big enough to have a Gardner engine fitted.
Here is a link that offers all the models and HP:

Don't have many answers, I only know what I found out from my inspections and the survey. I can't just jump on the boat and have a look as it is currently 3000 NM away. I will be going over there to sail her back in 2 weeks time.

Max RPM in the workshop manual is stated at 1700, but sea trial saw her doing 5.9knts at 900 RPM and 7.8knts at 1100 RPM. I doubt I would ever need to push much over that.

Fresh water cooled.

Gear box... no idea.

Possibly the marinised version was detuned somehow?

Re: Gardner LW5

Found your vessel online; looks like a very tidy well engineered unit. The motor is fitted with a gardner 2UC G/box ,it is better than a fair a chance it would be a original marine engine they also had a alloy sump.

The original 5lw had a rating of 70hp @ 1300, they latter became 76hp @ 1500. Industrial & road transport engines 96 hp @ 1700. A lot of marine engines have been taken out to this rating.

I guess at this time of year you will be going home via the bight, hopefully the weather will co-operate.

Leave Murphy on the Wharf!
